To review human immunodeficiency virus (HIV) risk reduction interventions among injecting drug users (IDUs) that have adopted a network approach.
The design and outcomes of selected network-based interventions among IDUs are reviewed using the network concepts of the dyad (two-person relationship), the personal risk network (an index person and all of his or her relationship), and the "sociometric" network (the complete set of relations between people in a population) and community.
In a dyad intervention among HIV-serodiscordant couples, many of which included IDUs, there were no HIV seroconversions. Participants in personal risk network interventions were more likely to reduce drug risks and in some of these interventions, sexual risks, than were participants in individual-based interventions. Sociometric network interventions reached more IDUs and may be more cost-effective than individual-based interventions.
Network-based HIV risk reduction interventions among IDUs, and others at risk for HIV, hold promise and should be encouraged.
回顾采用网络方法的注射吸毒者（IDU）中降低人类免疫缺陷病毒（HIV）风险的干预措施。
运用二元组（两人关系）、个人风险网络（一个索引人物及其所有关系）以及“社会测量”网络（人群中人与人之间的完整关系集）和社区等网络概念，回顾IDU中选定的基于网络的干预措施的设计和结果。
在许多包含IDU的HIV血清学不一致夫妻的二元组干预中，未出现HIV血清转化。与基于个体的干预措施参与者相比，个人风险网络干预措施的参与者更有可能降低毒品风险，在其中一些干预措施中还能降低性风险。社会测量网络干预措施覆盖了更多的IDU，并且可能比基于个体的干预措施更具成本效益。
IDU及其他有HIV感染风险者中基于网络的HIV风险降低干预措施具有前景，应予以鼓励。
